I'm trying to understand FLASH rom. The knowledgebase (it was not down!!!
For that alone I had a party) didn't quite answer some questions I had.
Please help!
TRG's InstallPro app allows a PRC/PDB to be installed into the 'free' flash
ROM of a Palm device.
They define the 'free' area as the memory that is not used up by the OS. :)
That piqued my interest. I was wondering how much unused FLASH storage
exists on the various flash-based Palm devices (all except for the IIIe, I
surmise?), and whether or not it's prudent to utilize it. I read that
anywhere from 512K to 2M can be FLASH ROM.
>From what I recall, this is where hardware vendors can put their own
specific 'versions' of the PalmOS on their specialized device. This is what
we did on the SPT1740 device. In any left-over room, a developer can risk
putting his/her app there to have it persist even the dreaded hard reset.
But who's to say how much space is available, and how much of it might be
eaten up by PalmOS updates or other Palm stuff? I wonder what happens if
you decide to put your app in FLASH, and a PalmOS update eats into a few
hundred bytes of your app. Yuck.
Obviously not something to use if you don't fully understand it (hm, much
like patching traps)
Thanks for the bandwidth,
